A flight attendant has revealed the grim reason why passengers should try to avoid using the toilet on airplanes.

The employee, who did not disclose her airline, candidly discussed her experiences dealing with airplane toilets.

In a Reddit ‘Ask Me Anything’ Q&A, the 33-year-old, using the username sassy_chick01, shared her insights.

One user asked her about the health and hygiene standards of plane toilets, writing: “Real talk: How dirty are the planes? What about the bathrooms?”

She replied: “Planes are filthy. They don’t disinfect them.

“Bathrooms are basically just wiped down quickly between flights.”

Another user asked: “Do you have to use the same lavatories as passengers? I don’t think I’ve seen an FA [flight attendant] use the lavatory.”

The flight attendant confirmed that the cabin crew do use the same toilets as passengers.

She added: “Most of us try to avoid going in there if possible.”

The attendant also shared the “most inappropriate” thing she has witnessed whilst working – “mile high club stuff” and the scariest incident she’s dealt with.

She said: “I thought a passenger was dead, [but] he had fainted and couldn’t wake up.”
